Definitions

  • the present invention related to a timed faucet including means for continuously changing the delivery time and flow-rate thereof.
  • a faucet according to the preamble of claim 1 is disclosed in document US 3 674 237.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a timed faucet, with means for changing the delivery time and flow-rate thereof, allowing to adjust, in a very simple manner and without disassembling any components of the faucet, the water inlet time, the flow-rate thereof and simultaneously to hold in a cleaned condition the water passage.
  • a main object of the present invention is to provide such a timed faucet which is directly provided in its inside with any fittings required for a proper operation of the faucet, without the requirement of providing additional elements.
  • Yet another object of the present invention is to provide such a timed faucet which, owing to its specifically designed constructional features, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a timed faucet, including means for continuously changing the delivery time and flow-rate thereof, which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a timed faucet including means for continuously changing the delivery time and flow-rate thereof, characterized in that said timed faucet comprises, inside a valve body defining an inlet and outlet duct, a shutter piston delimiting a load chamber communicating with said inlet through adjusting means for adjusting the delivery time of said faucet, said adjusting means being adapted to be calibrated from the outside of said valve body, further changing means for changing the flow-rate of said faucet, independent from said adjusting means and arranged in said inlet being moreover provided.
  • the timed faucet including means for continuously changing the delivery time and flow-rate thereof, according to the present invention, comprises, inside a valve body 2, an inlet for introducing an inlet flow A and an outlet duct 32.
  • the outlet duct 32 is coupled, through a cap 31 and a gasket 30, to the valve body, from which a water flow B is delivered.
  • a shutter piston 1 Inside the valve body is provided a shutter piston 1, including an engagement gasket 8 engaging with a tube facing the outlet duct and having a further gasket or seal 4.
  • a sealing or tightness gasket 26 operating inside said valve body.
  • the shutter piston 1 defines a load chamber Y, which communicates with a duct therethrough a load flow C is conveyed, through the interposition of adjusting means for adjusting the delivery time, which adjusting means will be disclosed in a more detailed manner hereinafter.
  • a control rod 19 including an inlet hole 18 for allowing water to enter said control rod, which is connected with an inner tube 29, leading to the outlet duct.
  • the control rod as shown, comprises further gaskets 22 and 23 for providing a sealed relationship with respect to the screw element 14, inside of which said control rod can slidably move.
  • the control rod is driven by a control rod spring 27, abutting between a shoulder of said control rod and a spring ring element 28, arranged at the bottom end portion above the region affected by a sealing gasket 6.
  • a push-button 20 To said control rod is coupled a push-button 20, affected by a push-button spring 21.
  • the screw element is coupled to the mentioned valve body through the interposition of a further gasket or sealing element 25.
  • the adjusting means for adjusting the delivery time substantially comprise an insert element 16, thereabout is provided an adjusting screw for adjusting the delivery time, which adjusting screw 15 is coupled through a further gasket 14.
  • the insert element comprises, at the bottom thereof, a filter 11 and sealing gaskets 12 and 13 providing tightness with respect to the outside environment.
  • the adjusting screw comprises a stem controlling a calibrated hole, by means of which is changed the load water flow F through the adjusting insert element.
  • a passage hole 33 is provided, communicating the flow F with the flow C conveyed into the chamber Y.
  • Changing means are moreover provided for changing the faucet flow-rate, said changing means being independent from the adjusting means and being arranged in the inlet of the water flow A.
  • Said adjusting means comprise a rotary valve for adjusting the water flow-rate, said rotary valve 9 defining a rotary duct, which can be rotated through a rotation range Z, in order to control the inlet duct flow.
  • a gasket 7 with a related Seeger ring 5 and a top valve guide element 10, allowing to hold in position the flow-rate adjusting valve.
  • the assembly comprises moreover on the valve body an air inlet hole 3.
  • the pressure exerted on the bottom surface of the piston will be greater than that on the top portion thereof, thereby providing a displacement force displacing or driving upward said piston, to clear the water passage area, thereby providing the outward directed water flow B.
  • the air inlet hole 3 is moreover provided, which will generate, with the timed faucet in its open condition, an air flow D, provided for increasing the water outlet rate.
  • the closing operation (figure 4) will occur as the pressure applied to the top portion of the piston by the flow C will be again greater or larger than that on the bottom surface of said piston, thereby providing an urging force driving downward said piston.
  • the screw element having a frustum of cone shaped end portion, the sealing coupling of which is provided by two O-ring elements, allows to change the amplitude of the passage section providing the water flow F by operating said screw element.
  • Such an adjustment can be performed, in a very simple manner, by a screw driver, after having removed the covering element 17.
  • Upstream of said valve is arranged the filter 11, filtering possible impurities, thereby preventing problems. related to possible lockings of the passage sections.
  • the invention provides a timed faucet including a very reduced number of component elements and having greatly simplified constructional features.
  • the used materials, as well as the contingent size and shaped can be any, depending on requirements.
